Blizzard’s current claim that they have 11.5 million total subscribers while technically accurate is misleading because not all subscribers are paying the same to play WoW. Some of us already familiar with the Asian pay per play scheme for MMOs but I highly doubt the average WoW gamer in the U.S. and Europe would be aware of this.
For every dollar a non-Asian WoW subscriber pays for WoW an Asian subscriber pays 6 cents. The reality is that all WoW subscribers are not equal; they do not have equal representative value for purposes of comparison. Yet for purposes of marketing and to the untrained eye: a subscriber is a subscriber.

If there are 5.75 million WoW subscribers in Asia only bringing in 6% of the total worldwide WoW revenue then I have calculated that in terms of “real” subscribers the Asian market is the equivalent of approximately 370, 000 U.S. and European subscribers who pay to play by the month. Combine this with the actual numbers of U.S. and European subscribers and you’d have an adjusted total of approximately 6.12 million subscribers playing WoW — not the 11.5 subscribers that they claimed in their last press release.
The resulting 6.12 million subscribers is a bit more than half the number that they claim that WoW actually has. Suddenly WoW doesn’t look like a social and cultural juggernaut. Are Westerners Subsidizing Asian MMO Gamers?

Given the puny amount of revenue that Blizzard is generating from WoW in Asia, why aren’t they charging Asians more and the rest of us less? Fair is fair.
Another issue worth bringing up is because of the millions of Asian gamers with access to WoW we now have the scourge of gold farmers with ties to organized crime syndicates. Player accounts are hacked, stolen and used to farm gold. They also disrupt gameplay within WoW with their spam. Blizzard spends a considerable amount of time and resources dealing with compromised accounts.
Given all of these problems and inequities, why are western subscribers still subsidizing Asian gamers?

if they have 11.5 million subs, they have 11.5 million subs no matter if every single one of them pay a different price.

also, If gold spam "disrupts" anyones gameplay they are pretty stupid, it was never "disruptive" of gameplay, and in fact at times it was hilarious (floating web site names made out of orc bodies anyone?).

I have a friend who lives in china and her monthly salary is about $350, which is less than what someone with a normal salary in sweden for example would make in 3 days, and that sir is why you cannot charge them €12.99

"The story begins in 1913, when the government of China began issuing bonds to foreigninvestors and governments for infrastructure work to modernize the country. As the country fell into civil war in 1927, paying these debts became increasingly difficult and the government fell into default. Even so, in April 1938, the Nationalist government of China began to issue U.S.-dollar denominated bonds to finance its war against Japan.
The government issued these bonds into 1940, and the U.S. government further provided a $500 million credit to China in March 1942. China doesn’t appear to have repaid this debt either, according to State Department records.
The new Communist government in 1949 refused to pay any of these claims. In 1979, as part of normalizing relations, Washington released government financial claims regarding the expropriation of American property and appears to have dropped the matter of the war debt entirely.
However, it is one thing for government decision-makers to let go of government debt. And it is another thing for individual citizens to press their claims. Some U.S. investors tried to sue the Chinese government in the 1980s and 1990s, but the Foreign Sovereign Immunities Act makes it hard because the law generally says U.S. courts do not have jurisdiction.
China lost an initial summary judgment for failing to appear in court but, with the urging of the U.S. State Department, later appeared in court and successfully argued U.S. courts did not have jurisdiction.
Today, the Chinese bonds held by U.S. investors may be worth as much as $750 billion, according to Jonna Bianco, president of the American Bondholders Foundation."
